Specification of Letters Patent.

Application filed February 10, 1910. Serial No. 543,076.

To all whom it may concern.

Be it known that I, KoRNELIs vAN Koor, a subject of the Queen of the Netherlands, residing at Clara City, .in the county of Chippewa and State of Minnesota, have in- Other objects of the invention are to p roduce a reel of the character described which may be very readily adjusted to varying conditions of the grain to be operated upon, whether the latter be high or low, standin or down, and which shall be so constructed that the grain-engaging teeth will readily and surely become disengaged from the grain at the proper' time, thus avoiding danger of choki g.

With these and other ends in view which will readily appear as the nature of them-- vention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and ticularly pointed out in the claims In the accompanying drawings has been illustrated a simple and preferred form'of parthe invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the invention may be resorted to when desired.

V 3 In the drawings,Figure 1 is a side eleva-' tion showing a portion 6f the harvester frame equipped witha reel constructed in accordance with the invention, said reel be-.

ing adjusted to operate down grain. Ifi'g. 2 is a similar view, showing the reel adjusted to operate standing grain. Fig. 3 is a! topplan view, showing the reel detached. 4 is a side view in elevation, showing a detail of the invention.

Corresponding parts in the several figures are denoted by like characters of reference.

The frame of the improved reel may con sist of side members 1', l which are-connected and reinforced by means of diagonal braces 2, 2, whereby said side members are also spaced apart. The side members 1, 1 afford bearingscfora transversely disposed'shaft 3 which is also supported for rotation upon the frame of the machine, as indicated at 4, thus supporting the .reel frame pivotally with reference to the machine frame andat a suitable distance above the platform 5,

The tide members of the frame are provided adjacent to their front and rear ends with bearings 6 and 7 wherein are supported stub shafts'or spindles 8,9carryiog sprocketwheels 10-and 11. Similar sprocket wheels 12 are carried by the shaft 3, said sprocket Wheels 12 being disposed in longitudinal alinement with the sprocket wheels 10 and 11. vChains 13, which are guided over the sprockets 10, 12 and 11 adjacent to the two sides of the frame, are provided at intervals with slats 14; having grain-engaging teeth 15 the points of which aie curved in slidably supported upon one of, the side members of the reel frame, said stop member being connected by a link 20 with a cam lever 21 pivotally supported upona handle b51122 which is secured upon the side member of the reel. frame. It will be readily seen that the stop member 19 may be con- .veniently disconnected from the segment rack 18, thus permittinglther'eel frame to be tilted by means of the handle bar 22 to any of the different positions indicated in the-drawings or to various other positions that may be desired.

The shaft 3 is provided at oneend with a sprocket wheel 23 enabling it to receive mo- ;tion by means of a chain or link belt from some driven or rotary part of the harvester structure.

From the foregoing description, taken in connection with the drawings hereto annexed, the operation and advantages of this invention will be" readily understood. It will be seen that by tilting the forward end of the reel 'frame'in a downward direction, grain that is down will be engaged bythe chains, thus elevating suchgrain'and pre teeth 15. upon the slats connecting the endless senting it properly to the cutting mecha- The tooth-carrying slats of the lower leads of the chains in passing over the idlers 16 will be tiltedin such a manner that the teeth of said slats will be effectively discon-' nected from the grain, thus positively preventing choking of the device While in action.

Having thus described the invention, What is claimed as new, is v 1. In a grain harvester, a frame, a grain platform, a driven shaft supported for rotation in the fraine'above and adjacent to the platform, a reel frame supported pivot ally upon the shaft, sprocket Wheels upon the shaft adjacent to the sides of the reel frame, sprocket wheels supported adjacent to the sides of the reel frame at the front and rear ends thereof, chains guided over the. sprocket wheels, slats connecting said chains, teeth upon said slats having hook-shaped points curved in'the direction of the movement of the chains, and guiding sprockets intermediate the front and rear ends of the frame and. above the normal path of the to deflect said chains upwardly from the platform and to deflect the teeth of the slats toward the axis of the guiding sprockets, said guiding sprockets being supported above the normal path of the lowerleads of the chains sutficient-ly so that the chains after leaving the highest. position will place the hook-shaped teeth in discharging PQ sition.
